(2) Using PWM output mode
(a) Changing the PWM waveform while the counter is incrementing
To change the PWM waveform while the counter is incrementing, write to the TPnCCR1 register after
changing the waveform setting. When rewriting the TPnCCRa register after writing to the TPnCCR1
register, do so after the INTTPnCC0 signal has been detected.
In order to transfer data from the TPnCCRa register to the CCRa buffer register, the TPnCCR1 register
must be written.
After data is written to the TPnCCR1 register, the value written to the TPnCCRa register is transferred to
the CCRa buffer register in synchronization with clearing of the 16-bit counter, and is used as the value to
be compared with the 16-bit counter value.
<1> To change both the cycle and active level width of the PWM waveform, first set the cycle to the
<2> To change only the cycle of the PWM waveform, first set the cycle to the TPnCCR0 register, and
<3> To change only the active level width (duty factor) of the PWM waveform, only the TPnCCR1 register

then write the same value to the TPnCCR1 register (that is, the same value as the value already
